Answer:
The correct answer would be "The plant is a fern, and sporophyte is its dominant phase".
Ferns refer to the lower plants which do not bear flowers, have leafy or feathery fronds, and they reproduce by spores.
They show alternation of generation in which sporophyte is the dominant stage.
The mature diploid sporophyte releases haploid spores with the help of meiotic divisions.
The haploid spore divides by mitotic division and matures into a haploid gametophyte. The single gametophyte bears antheridium and archegonium which release flagellated male gametes and egg (female gamete) respectively with the help of mitotic division.
The gametes fertilize to produce a diploid zygote.
The zygote divides mitotically and matures into the diploid sporophyte.

Answer:
d. Exercise increases the body's demand for oxygen.
Explanation:
More oxygen is needed during exercise by the body as compared to normal condition because our body needs energy which is only generated in the process of cellular respiration. In cellular respiration, glucose molecule is broken down by mitochondria of the cell and energy is generated in the form of adenine tri phosphate (ATP) which is used for performing muscular activity. So that's why oxygen requirement is more during exercise.
